Description

TECHNICAL FIELD

[0001] The application relates to the technical field of motor production, in particular to a mounting device for a brush socket of a motor end cover. BACKGROUND

[0002] The brush socket in a motor is part of the brush device, and mainly functions to fix and guide the brush, and ensure that the brush maintains good contact with the commutator or collector ring. In a DC motor, the brush socket is usually designed on the end cover or the base of the motor, and is used in cooperation with the brush. The brush is tightly attached to the surface of the commutator through spring pressure, so as to realize electrical connection between the rotating armature winding and the external circuit, and to lead the electromotive force and current of the armature winding to the load or power supply of the external circuit. The design of the brush socket needs to consider the size and shape of the brush, so as to ensure the stability and reliability of the brush during the operation of the motor. The structure and material of the brush socket also affect the wear of the brush and the operation efficiency of the motor.

[0003] REFERENCE Figure 1 A motor end cover 01 comprises a mounting portion 011 in a U shape and connecting ear plates 012 arranged at two ends of the mounting portion 011, the connecting ear plates 012 are provided with connecting through holes 015, the motor end cover 01 is made of plastic. The side wall adjacent to the connecting ear plate 012 of the mounting portion 011 is provided with a mounting hole 013, a copper brush socket 02 in a cylindrical shape is in interference fit with one in each mounting hole 013, and the two brush sockets 02 are coaxially arranged. The mounting portion 011 is provided with a positioning hole 014 on the side wall adjacent to the mounting hole 013.

[0004] When the brush socket is mounted, an operator needs to first place a brush socket in the mounting hole on one side of the mounting portion, hold the end cover and place it under the pressing device, and then the pressing device is lowered to press the brush socket into the mounting hole of the end cover. After the installation of the brush socket on one side is completed, the end cover is turned over, and the above operation is repeated to install the brush socket on the other side of the mounting portion.

[0005] According to the related technology in the above, the inventor considers that in the process of mounting the brush socket of the above motor end cover, on the one hand, the mounting efficiency is low because only one brush socket can be mounted at a time by using the mounting method, and on the other hand, the U-shaped mounting portion is prone to deformation during pressing and is likely to affect the operation safety of the operator.
